K-Tuned Swivel Neck Thermostat Housing

MRSP: $169.99

Applications: Fits all K20A/Z and K24A Series engines.

K-Tuned has the solution to your lower rad hose problems. Some of the motors we have received came with the oem plastic water neck broken. Until now, you could only order a replacement part from Honda/Acura. Problem is they only sell the housing complete with the thermostat, which is pretty expensive and it doesn’t provide any real benefits. If your housing isn’t broken then you still have to get the right hose, with the right angles and mate it to the rad. After that, you have to figure out where to put your fan switch and in the past the only option was to use a special inline aluminum hose adapter.

This product solves all these problems and gives you some options when doing your swap. The housing swivels, allowing you to position the water outlet angle before it is tightened down. The provided custom made fitting is the same size as the oem rad hose on one end, and is threaded for an AN fitting on the other end. This allows you to use whatever size fitting you need for custom installations. If you want to use braided hose with AN fittings, this housing will bolt on easily and with the right adapter threaded in, you’ll be all set. The housing has three ports in the body, one for your fan switch, a 1/8 NPT port for gauges etc. and also ½ NPT port for our optional recirculation fitting. 2 NPT plugs are included in case the ports remain unused. The swivel neck comes pre-assembled with a quality Stant thermostat (180 deg.) which is held in place with a "C" clip. The kit uses a standard size thermostat that you can easily replace with anything in the 160-195 degree range.

Last but not least, this was a bonus we found while designing it. We noticed that by adding one more hole to the flange you could completely remove the oem black plastic housing from the block and delete the heater core hoses. When set up this way, our thermostat housing is bolted directly to the oem aluminum water pump housing. This is perfect for race car applications.

Very nice, will work perfect for cars that delete there heater cores. No more looping the hose, now plug the head and buy this piece, you have one clean install.

Verry nice pice.

"Mark P" As far as not running the water pipe to the head, I don't think that is a good idea.

Thats the idea. This piece also takes the place of the ugly rad hose insert allowing you to put the fan switch directly on the rad neck.

Verry nice pice.

What is the problem with deleting the water hose to the head?

if you are not going to use the two auxiliary 1/8 NPT ports, do we just need to buy plugs or what?

I'm currently running my car with the head plugged off with no problems, but I don't daily mine.

question, Why is it not safe to run this set up bolted up to the waterpump housing directly for street use?
its safe, but it will delete the lines for your heater core, so you wont have heat..

cool product

Wow, that is one crazy design. Very cool. I do have one question though...

For the coolant temperature sending unit, doesn't it have to be grounded around the threaded part? I can see it being grounded for the race application since it's touching the water pump, but wouldn't the plastic thermostat housing insulate it from being grounded?

The coolant temperature sending unit belongs on the upper rad hose to read the water temperature more accurately. You don't want to put it on the lower adapter, that was done just for the photos.

I was just going to say that. The temp gauge sending unit has to be before the thermostat. Otherwize it will not read hot untill the thermostat opens.
